Mars on the rocks: NASA's Mars Reconnaissance Orbiter found that thick masses of buried ice are quite common beneath protective coverings of rubble. The spacecraft's Shallow Radar system has taken more than 250 observations of the study area, which is about the size of California. "The hypothesis is the whole area was covered with an ice sheet during a different climate period, and when the climate dried out, these deposits remained only where they had been covered by a layer of debris protecting the ice from the atmosphere," said Jeffrey Plaut of NASA's Jet Propulsion Laboratory.
